Our weather is still being controlled by an upper level low in Northeast Canada. This trough will continues to supply cooler air in from Canada into New England for the next several days, even though afternoon highs will gradually start to moderate. Once again, the day is starting off cool near freezing at dawn with the clear, calm conditions. Luckily,days are sunny and milder as the late April Sun will warm the ground and the air around it. High pressure to our north will supply the dry, clean, stable Canadian air with highs climbing into the 50's to near 60 during the afternoon.
A front is stalled south of New England, the boundary separating the cooler air over us, from the southern warmth of the southern and Mid-Atlantic states. Showers and storms will continue to ride along this boundary. A wave will develop and start to push a bit closer towards New England later Today and tonight. A deck of clouds will begin to spread into New England later today and will be with us through early Friday. High pressure to our north will flex it's muscle and keep the sunshine in place for Friday, but also wrapping in a cooler onshore wind which will keep temps in the 40's at the beach and Lwr-mid 50's inland.Temperatures will be milder Saturday with a warmer west wind and highs climbing into the Lwr-mid 60's!
Another wave will track along the stalled front and approach Late Sunday into Monday. This time, the upper low will be farther east and will open the door for the slug of rain to track into the Northeast. The concern is enough cold air will be in place for some of the rain Monday to mix with wet snow in the north country and higher elevations. It will be a chilly raw day again.
A trough in the upper level wind pattern in the Northeast will remain quite persistent through at least the middle of the month. This will help to prevent any big Spring Warm up in the near future, and even some days depending on precipitation arrival and the airmass in place, it just may be cold enough for a few wet flakes to mix in...even as we head into May. The warmth will be a struggle for now until this blocking pattern finally shifts east and loses it's grip. There signs that next week may remain unsettled with still a few more chances at showers.
